Restore clean, airtight thermal fusion lines along your storage pouch boundaries and fix weak bag closures with this premium WCV300 chamber vacuum sealer 11-inch thermal silicone seal bar rubber strip component. Factory engineered by Waring, this high-temperature flexible backing block inserts straight into the system seal bar tray to provide uniform mechanical counter-pressure when the sealing wire cycles. Swapping out a scorched, indented, or worn rubber track with this fresh original hardware component ensures flat compression contact, stops uneven pouch melting, and protects bagging lines from leakage risks.
Resilient Thermally Calibrated Matrix: Fabricated from specialized commercial elastomer compound that holds its flat face configuration under extreme heating element pressures.
11-Inch Full-Width Coverage: Designed with a precise linear length that fits flush within the sealing bar framework, ensuring zero pressure dead-spots across the entire pouch width.
Impact-Absorbing Backing Cushion: Features a high-rebound internal structure layout that dampens repetitive lid slamming forces to shield internal wire routing paths.
